Build and test Kubernetes API server

This page explains how to build and publish the API server which contains the WASM extension.

Dependencies

To run the tests and build the API server you need the following tools:

  • System tools
    • Git
    • Curl
    • Make
    • C compiler (cc)
    • Rsync
apt-get install git curl gcc make rsync

Install wasm32-wasi target:

rustup target add wasm32-wasi

Run tests

Clone the extended API server code:

git clone -b wasm [email protected]:dvob/kubernetes.git
cd kubernetes/

Before you can run the tests for the pkg/wasm package you have to run the prepare script which builds the test modules and downloads some Kubewarden policies (modules).

cd pkg/wasm/testmodules/
./prepare_integration_tests.sh

Then you can run all WASM related tests in the ./pkg/wasm directory:

cd $( git rev-parse --show-toplevel )/pkg/wasm
go test -v ./...

Build & Publish

From the root of the repository you can run the build of the whole Kubernetes project:

cd $( git rev-parse --show-toplevel )
make quick-release-images KUBE_BUILD_PLATFORMS=linux/amd64

This publishes the build artifacts to the _output directory. For the API server you can find the following artifacts:

  • Binary: :/_output/release-stage/server/linux-amd64/kubernetes/server/bin/kube-apiserver
  • Docker image (TAR): ./_output/release-images/amd64/kube-apiserver.tar

Depending on your cluster setup you either need the kube-apiserver binary or the Docker image. In the case of a kubeadm Kubernetes installation you need the Docker image.

To use the Docker image you have to publish it to a Docker registry. In the following example we publish the image to dvob/kube-apiserver:dev.

docker login
docker load -i ./_output/release-images/amd64/kube-apiserver.tar
docker tag <name of loaded image> dvob/kube-apiserver:dev
docker push dvob/kube-apiserver:dev

To publish the TAR directly you can also use the tool crane:

crane push _output/release-images/amd64/kube-apiserver.tar dvob/kube-apiserver:magic-example

Run

See Setup Kubernetes cluster for instructions on how to setup a Kubernetes cluster and configure a custom API server image.
